Backup folder structure per user

I already have google drive as additional destination in backup settings which already working fine.

I just need the following feature to be added to it:

I need the backups to be sorted in the backup folder firstrly sorted in folders per account name & in each of these folders the account's backups per day.

Backup/dates/usersfolders -> Backup/userfolder/dates (user backups)

Why do I need this?

I need to share with my customers through Google Drive their seperate cpanel folder, for safe keeping.

This is a feature I want to give to them for their peace of mind.
Everyone asks: What if something happens to you? I have my whole company hanging on your shoulders...
